The main solar rebate program in Australia is the Small-scale Renewable Energy Scheme (SRES), which provides rebates for small-scale solar panel, wind, and hydro systems. Under the SRES, households and businesses that install eligible solar systems can create Small-scale Technology Certificates (STCs) based on the amount of renewable energy generated. These STCs can then be sold to electricity retailers, who are required by law to obtain a certain number of STCs each year.

The amount of Rebate received through the SRES depends on various factors such as the location, size, and efficiency of the system installed. The Rebate is typically calculated based on the number of STCs created, with each STC representing one megawatt-hour of electricity generated by the system over its lifetime.

In addition to the SRES, some states and territories in Australia also offer additional rebates and incentives for Solar power installations. For example, the New South Wales government offers the Solar Homes program, which provides interest-free loans and rebates for eligible Solar and battery storage systems.

Overall, the availability and amount of rebates for Solar power systems in Australia can vary depending on the location and the specific program being offered. It is recommended to check with local authorities and reputable Solar installers for the most up-to-date information on available rebates and incentives.
